Question

how long can milk be left out the fridge before going bad

Answer 1

Milk should not be left out at room temperature for more than two hours. If the temperature exceeds 90°F (32°C), this time is reduced to just one hour. After that, bacteria can multiply rapidly, increasing the risk of spoilage and foodborne illnesses. If milk has been left out for longer than the recommended times, it's best to discard it to ensure safety.
